ELECTRIC-ARC LAM P.

SPECIFICATION forming part of Letters Patent No. 615,407, dated December 6, 1898.

' Application iiledJune 3, 1895. Serial No. 551,491. (No model.)

To @ZZ whom it may concern:

Be it known that I, MosEs S. OKUN, a citizen of the United States, and a residentof New York city, county and State of New York, have invented certain new and useful Improvements in Arc-Lamps, of which the following is a specification.

One portion of my invention relates more particularly to the class of arc-lamps wherein the arc is sustained in a closed globe to eX- clude air from the carbons and wherein gas (OO and CO2) is formed to retard the consumption of the carbons and the invention has for its object to permit the carbon to feed freely and properly, while retarding t-he entrance of air into the globe.

The invention consists in a closed globe having a small opening leading into it to permit the passage of a carbon, While retarding the entrance of air, said opening serving to guide the carbon, combined with carbonfeeding mechanism and a pivotal connection between the carbon and its feeding mechanism, whereby the carbon may pass freely through the opening in the globe to permit of its proper feeding'.

Referenceis to be had to the accompanying drawings, forming part hereof, wherein- Figure l is a side view, partly in section, of an arc-lamp embodyi-ng my invention, showing the devices for connecting the carbon with its carrier. Fig. 2 is a similar view,

, partly in section, of a modiication; and Fig.

3 is a side elevation, partly in section, showing improved devices for retarding the consumption of the carbons.

Referring now to the accompanying drawings, in which similar numerals of reference indicate corresponding parts in the several views, the number 1 indicates a globe within which the arc is to be formed.

2 is a suitable frame or support therefor, and 3 is a suitable mechanism, casing, or box carrying said frame or support.

The globe 1 may be sustained in any suit` able manner. In Fig. 1 I have shown the lower end of the globe 1 open and resting on a plate or disk 4, carried by the frame or support 2, by which plate the lower end of the globe is closed. At its upper end the globe 1 has a small opening 5 leading into it to permit the passage into said globe of the upper carbon 6, while retarding the entrance of air into said globe through said opening around said carbon. This opening 5 maybe formed in any suitable manner. In Figs. 1 and 3 I have shown the globe l at its upper end as provided with a cover, disk, or plug 5a, in which the opening 5 for the passage of the carbon is formed. In this case the cover, disk, or plug 5 closes the upper opening or open end l of the globe 1. In Fig. 2 the opening 5 is formed directly in the upper end of the globe 1. In any case, however, no matter how formed, the globe l will have an opening, as 5, leading into it for the passage of the carbon 6. This opening 5 will be of such a size that the carbon will lit comparatively snugly therein, yet with sufficient freedom to enable it to move longitudinally therein for regulating the arc. The opening 5 in the globe 1 guides the carbon, and in order to pre* vent the carbon from having side pressure on the walls of said opening 5, which would create friction were it rigidly connected with a carbon-feeding rod, and thus prevent free feeding of the carbon, I connect the carbon 6 with its feeding devices or mechanism by a pivotal connection which will allow the carbon to pass freely through the opening 5 at all times.

7 is a carbon carrier or feeding rod, and 8 is a carbon-holder which supports the carbon 6. The connection between the carbon feeding rod or carrier and the carbon-holder is such that it will allow the carbon` to have motion of translation or progressive motion laterally. Vith this arrangement the carbon can assume any necessary positions in order to allow it to feed freely into the globe 1 through opening 5 without being retarded by frictional contact with the walls of the opening 5. This opening 5 in the globe also serves to guide the carbon in line with the lower carbon 6.

The carbon G is yieldingly supported by ball-and-socket joints 7d 7C, connecting the carbon-holder 8 with the carbon-rod 7 fl; but the positions of the ball and socket may be reversed. Such two joints interposed between the rod 7 and holder 8 permit the carbon to have motion of translation laterally in all directions, as well as pivotal or oscillatory move! ment.

ICO

In Fig. 2 the ball 7f is replaced by a :flat

disk or extension which receives the socket 7e, the upper edges of which socket are inwardly flanged, so as to allow the carbon to have side movement or motion of translation laterally to reduce frictional contact between the carbon and the walls ot' the opening 5 of the globe l. The lower carbon Gf maybe supported in any suitable manner.

In Fig. 3 the lower end of the globe l is open, its upper end being secured to the cover or disk 5, from which it depends, the opening 5 being formed in said cover or disk to guide the carbon (i. The cover or disk 5 rests on a plate, ring, orcover 5, which is car ried by the frame or support 2, the cover or plate 5C having an opening 5d for the passage of the globe or shield l. 1b is an outer proteet-ing globe or envelop which is supported by the cover or plate 5, as by clips I2, which permit ready removal of the globe I or otherwise. The lowercarbon holder 8 is shown carried by the globe l", so as to prevent ingress of air at that point. In the above-described arrangement a tight lit is made between the parts I and 5, as also between the parts 5Cand 5, to retard the admission of air to the globe or shield. lfVhen the globe or shield l is to be cleaned, it is only necessary to lift it from the cover or plate 5C without removing the globe 1b. The small inner globe or shield l retains the heat in proximity to the carbon-points to assist their incandescence, while keeping the hot air t rom the outer globe Ib.

It will be understood that in all the arrangements of globes shown the globe is tightly closed, so that gas will form therein to retard the consumption of the carbons, the presence of the carbon C in the opening 5 of the globe serving to retard the entrance of air therethrough, while said opening allows the carbon to feed freely therein in conjunction with the movable connection between the carbon-carrier and the carbon-holder.
